Acronis Universal Deploy in Linux

Acronis Universal Deploy can be applied to Linux operating systems with a kernel version of 2.6.8 or later.

When Acronis Universal Deploy is applied to a Linux operating system, it updates a temporary file system known as the initial RAM disk (initrd). This ensures that the operating system can boot on the new hardware.

Acronis Universal Deploy adds modules for the new hardware (including device drivers) to the initial RAM disk. As a rule, it finds the necessary modules in the /lib/modules directory of the operating system you are deploying. If Acronis Universal Deploy cannot find a module it needs, it logs the module’s file name.

Acronis Universal Deploy may modify the configuration of the GRUB boot loader. This may be required, for example, to ensure the system bootability when the new machine has a different volume layout than the original machine.

Acronis Universal Deploy never modifies the Linux kernel.

Reverting to the original initial RAM disk

You can revert to the original initial RAM disk if necessary.

The initial RAM disk is stored on the machine in a file. Before updating the initial RAM disk for the first time, Acronis Universal Deploy saves a copy of it to the same directory. The name of the copy is the name of the file, followed by the _acronis_backup.img suffix. This copy will not be overwritten if you run Acronis Universal Deploy more than once (for example, after you have added missing drivers).

To revert to the original initial RAM disk, do any of the following:

• Rename the copy accordingly. For example, run a command similar to the following:

  mv initrd-2.6.16.60-0.21-default_acronis_backup.img initrd-2.6.16.60-0.21-default

• Specify the copy in the initrd line of the GRUB boot loader configuration.
